I bought a few of these years ago. They are a small board that plugs into the back of a standard 1602 LCD board. They come with an ATMEGA88 which I changed out for an ATMEGA328P. They have a 74HC595 and a MAX232 to drive the LCD and RS-232 respectively. The LCD interface is SPI and it pulls all of the ports out to standard ETTEAM 10-pin box headers.
I find this form factor amusing and have tinkered with it but have never used this for a project.
This is an UNOFFICIAL AVR community.
This is a community for people who use AVR microcontrollers. This can include Arduinos, Arduino clones, Arduino like boards, and stand alone AVR chips and self-designed boards.
NOTE: If your circuit is doing something weird when you touch a wire or move your hand across it see this pinned post.
This is a community for everyone who is interested in AVRs and Arduinos from beginners to experts, kids to adults, hobbyists to engineers.
